Wagner reported that Flash is a photo- and video-sharing app that, like Snapchat, contains visual overlays that users can place on top of their content.

According to Wagner, the app was developed for users in emerging markets with poor data and WiFi availability. Facebook reportedly said the Flash app is “less than 25 megabytes” in size. The app launched Tuesday on Android in its first market, Brazil.

Facebook product manager George Wang told Wagner the social network plans to bring the app to other areas in the future, although he did not reveal which ones.

This isn’t the first time Facebook released an app that was similar to Snapchat. The social network debuted photo- and video-sharing app Slingshot in 2014, which allowed users to view their friends’ “shots” only after they sent them shots in return. Slingshot was shuttered in 2015.
